fb all whom t may coaccraf Be it known that l, .l'Aeon Bassi', a citizen of the United States, residing at Crestline in the county of Crawford and Statev o Ohio, have invented certain new and useful Improvements in Surfacing-Maese, of which the following is a specication.

My invention relates to new and use improvements in surfacing machines and more particularly to road building machines of the type in 4which the surfacing material, such as gravel, slag or crushed stone is discharged from a truck as the truclr is drawn along the road and uniformly spread over the road. More particularly my present invention is anattachment for a road buildin machine ofthe type shown'in a patent togli. M. Myers, 1,233,107, patented cduly l0, 1917. 'lhe primary object of my invention resides in the provision of an attachment for a road building machine of the character there shown Iwhich may be adjusted at will.

to vary not only the depth at which the material will be distributed but also the width of surface over which the materialwill be distributed.

A still further object of my invention is to construct a spreader attachment for the road build-ing machine of such a character that initial spreading of the material employed may be accomplished by the road building machine and secondary adjustable spreading of the material may be thereafter performed by the spreader.-

With these and other objects in view, my invention will trated in the accompany/mg drawings and then specifically pointed out in the claims which form a part of this application.

ln the drawings:

Figure 1 is a perspective view of my attac ent in use;

llig. 2 is a top plan view of the attachment;

higs. 3 and 3a together are `a side elevation of my improved attachment, the road mal chine to which it is applied being shown in section;

hig. 4 is a fragmentary sectional view talzcn on thefline t-t of Fig. 3.

Corresponding and like parts are referred to inthe following description and indicated in all the views of the drawings by the same reference characters.

ln order to insure a clear and accurateV be'more fully described', illusj of the yobstructions will, of course, of the material being spread.

attachment 'is designed both to provide" understanding of myV invention and its use l have illustrated it in connection with the road building machine previouslyl referred tosv In the drawings indicates a dumping truck of any suitable character having a tilting end gate 1l, Iand 12 indicates. as a whole the road building machine. This road buildingmachine is fully described in the patent referred to and anyv detail eXplana-' tion of lit is, therefore, unnecessary. Primarily the machine comprises a hoppershaped casing' open at its top and bottom and supported at its front by wheels 13 and` at its bottom by runners or -shoes 14. This hopper or casing is connected by ,chains l5 to the truck at any suitable point, suchnas to the rear axle 16 and is so proportioned and located that the contents of the truck will be discharged into it. 'lhe back wall of this casing 1s provided near its bottom with an opening communicatingwith the opening; of theI bottom and extending throughout the length of the hopper and a vertically adjustable gate 17 is mounted upon the back'wall to vary the height of thisA openingso as to vary the depth of the layer oflcrushed stone or other material being spread which will be discharged during progress of the machine alongn the road.

lObviously, with a road building machine ofthe character thus briefly described although the depth of the material being discharged maybe adjusted there is no means for increasing the width of surface covered by the discharged material beyond the width of the hopper. Furthermore, any tilting hopper due to its engaging against vary the depth My improved means for increasing the width of the surface being treated, if desired and foryinsuring a more uniform spreading of the materialat the desired depth. l

Primarily my attachment includes/'a plow indicated as a whole by the numeral 18,

cludes the side members, blades or wings 19 which at their forward ends have pivot ears 20 formed with eyes 2l encircling the vertivcally disposedl part of a pivot shaft 22 the 'lower end of which is extended across the` open bottom of the hopper and formed with an upturned termnal23 by means of which it is connected to the inner face of the front wardlyfrom the hopper as best shown in Figsfl and 2. These blades or wings are preferably formed of wood, although metal may be employed, and at their lower forward edges are provided with reinforcing strips 25 of sheet metal of suitable thickness so that they may notbe unduly worn and splintered through engagementwith the material being spread.

Hinges 26 secured to the inner faces of the wings 19 near their free rear ends carry the i sections 27 of a spacer. brace 28 the abutting ends of which are formed with a' series of openings to adjustably receive bolts 2 9 or other suitable fastening meansy passed through `,clamping plates- 30 engaging against the front and rear faces of the brace 2 8. Nuts secure these bolts in place so that the brace as a whole may be adjusted in `length to vary the distance between the rear ends of the wingsand consequently vary the width of surface over which the material rwill be spread. Preferably hinges 31 se- "cured to the wings intermediate their 'length support sections 32 of a, second spacer brace 33 of like construction the abut# ting ends of which are adjustably connected by bolts 34 passed thrbugh clamping p ates 35.

.In order to facilitate vertical adjustment of the -forward end `f the plow upon the upivot shaft .22 I provide the bracket 24 with an arm 36 which ivotally receives one end of a hand lever 3 to which vis pivotedvthe upper end I'of a -lifting link 38 in-the form of a strap of metal the opposite end of which Y is secured to one of the eyes`2=1 by a boljtn39 or equivalent fastening device. This lever 1s provided with a hand latch mechanism 40 which coperates with a notched segment 41 either secured to or formed integrally with the bracket 24 'so that the lever may'y be locked -to temporarily support the forward end of the plow at any desired elevation.

Collars 42 are mountedupon the shaft 22 between certain ofthe pivot ears 21.and may 'be adjustably clampedupon the shaft by set bolts s o as to permanently 4lock the .plow againstl elther downward `or upward .movement after it has once 4beenl adjusted. .Be-s

'.f 1cause, ofthisjall' strain, during use of the ety A removed fromfthe hand latch eht 41.

means supporting the rear ends of the blades at the desired elevation I secure a triangular-shaped bracket 44 to the j ,be lockedV in adjusted position after being raised or lowered by the levers.

In order t0 prevent lateral swinging of the rear portion of the plow during use, such as might be occasioned 'by ununiform feeding of material in front of the plow or by any inequalities of the surface over which the material was being distributed I provide braces 56. Each of these braces includes a tubular member 57 pivoted as shown at 58 to one of the brackets 44 and a member 58 .telescoping with the first, and pivoted as shown at 59 to the forward portion of the ,hopper 12. Set bolts 60 or equivalent meanslserve to secure-the sections 57 and 58 of these braces in adjusted position, adjus'tability of these braces being necessitated as the free ends of the blades are to be adjustable toward and away from each other. Obviously, in place of telescopic braces 56 braces of the type shown at 28 and 33 may be employed between the hopper and blades or instead of the type of braces shown between the blades I may employ telescopic braces such 'as those employed between the hopper and blades. other words, I reserve the right to make an changes in details of construction, materia s employed, and the like,` which may fall within the. scope of the appended claims.

From the foregoing description taken in connection with the drawings the operation o'f my attachment will be readily appreciated. .Preferably the adjustable gate of the hopper is open to such an extent as to discharge material at a thickness somewhat greater than the actual thickness finally desired, while the plow is supported so that the lower edges of its blades are at just the elevation above the ground necessary to secure the desired thickness of the surfacing material. The blades are'adjusted toward and awa" .from each other to 'nsure spreading of t e material over the' desired width of surface and the truck is then started to cause discharge and spreading of the materi'al contained therein.
